γ- and δ-Chloroalkanamides were found to undergo lactamization readily when treated with potassium tert-butoxide in tetrahydrofuran. Raising the reaction temperature may encourage SN2 displacement reaction. On the other hand β-chloroalkanamides only undergo elimination, followed by dimerization and trimerization of the acrylamide initially formed.

Xanthone, thioxanthone, fluorenone, benzophenone, 2-benzoylpyridine, dibenzofuran, and dibenzothiophene were deprotonated using a base prepared in situ from MCl 2 ·TMEDA (M = Zn or Cd; TMEDA = N, N, N ′, N ′-tetramethylethylenediamine) and lithium 2,2,6,6-tetramethylpiperidide in a 1:3 ratio, as demonstrated by subsequent iodolysis. The different aryl halides were involved as partners in the N -arylation of pyrrolidin-2-one. In the presence of copper(I) iodide and tripotassium phosphate, and using dimethyl sulfoxide as solvent, the reactions could be performed in yields ranging from 40 to 70%. Most of the products were tested for their antimicrobial, antifungal, antioxidant, and cytotoxic (MCF-7) activity.
